A control axis on a standard controller needs an interface that works without a converter. The 4WRKE25R3-220L-3X/6EG24EK31/A1D3M accepts ±10 V directly, releases 220 l/min nominal flow and provides the closed mid position of spool symbol R3.
Benefits
- ±10 V command value, directly compatible with common analog controller outputs
- Spool symbol R3, ports P, T, A and B blocked in mid position
- 220 l/min nominal flow at 350 bar operating pressure
- External pilot oil return for a defined back pressure at the pilot stage
